Ravenswood
Morris, of Chicago, started doing it in autumn 1999. Recently
Traditional Fictional Morris (RTFM) was formed when a trio of former
Ravenswood Morris dancers moved to Boston in 2001 and wanted to
continue the tradition. They recruited a sufficiency of additional
personnel, and the dancing goes on.

Because we're Terry Pratchett fans. Because it's a silly thing to
do. Because we think balance in the world might be a good thing.
Because you don't have to get up so early to dance at dusk. Because
the sun might not go down if we don't. Or, in Terry Pratchett's own
words, to kill the trees and make the frost flowers bloom.

Audience members can do whatever they want, but a "tradition" has
sprung up of clapping silently (with the hands not quite making
contact).

What else happens after the performance is over?

When the final dance ends, the dances will lead a silent
procession through the labyrinth. Feel free to join in, just please
maintain silence. After emerging from the labyrinth, the dancers of
RTFM will quietly disperse, not to be seen again until next year.

However, as with that other dance that's done in the springtime,
if you do happen to see one of the dancers afterwards, it's also
traditional to buy beer for them.

Yes. After the AntiMorris, the evening's festivities are far from
over, because very shortly thereafter The Paper
Bag Mummers (PBM) convene just outside the gates of the growing
center and perform a short play. This performance marks the starting
point of PBM's annual "Oxford Street Souling Tour", in which the group
processes from the growing center to the far end of Oxford Street,
performing a soul-caking play wherever they find an audience along the
way. For more on the Paper Bag Mummers, check out their website, at
